Slotdevil 2008151502S 2,38 mm Clubsport rim 14x15x15 mm (2 pcs)

approx. 1.8 g, flange inside

2 Slotdevil rims for 3 mm axles and 4 Slotdevil reducers from 3.0 to 2.38 mm.

The reduction is done with a simple aluminum tube with an inner diameter of 2.38 mm and an outer diameter of 3 mm. A small flange serves as a stop or ideal spacer for the ball bearing. The inner diameter is deliberately slightly smaller than 2.38 mm. The first time it's pushed onto the axle, it's relatively tight. The soft aluminum gives way and adapts 100% and completely backlash-free to the axle. Then push the whole thing into the rim or gear with a little pressure. Here, too, the pressure results in a play-free adjustment and alignment to the axle bore. By tightening the 3 mm grub screw, a perfect connection is achieved. The grub screw presses against the aluminum tube and at the same time presses the aluminum tube firmly onto the axle. The whole thing requires only a few 10ths of a mm more space than the original 3 mm part, is feather-light and very inexpensive. The disadvantage lies in the slightly more difficult handling and in the limited multiple use. If you put the tube in z. B. has pushed a rim, then you can get it out again, but you can rarely use it again in another part afterwards. To be on the safe side, we include 4 reducers for 2 rims.
